l Claim.

This invention relates to a power and has more particular relation tothat type of power particularly designed for use in operating oil wellsin an oil eld from a central location.

Another object of the invention is to provide, in an apparatus of thecharacter described, a rotary table mounted to turn about a stationaryspindle and having thereon an eccentric spindle mounted to revolve aboutthe stationary spindle with a disk having a bearing on the eccentricspindle and which is thus mounted to oscillate about the stationaryspindle, and forming a 'connection for the rods leading to the variouspump jacks for operating the well pumps.

'Ihe disk above referred to l1s of such novel design that theconnections thereto of the rods leading to the pump jacks are inapproximately the same horizontal plane as that of the bearing of thedisk on the eccentric spindle and as that of the main bearing of therotary table on the stationary spindle.

A further object of the invention is to provide a power of the characterdescribed wherein the relative locations of the rotary table bearing,the disk bearing, and the connections of the pump jack rods to the diskare such that the stress of the load will be exerted in approximately astraight line through said bearings, so as to conduce to uniform wearand to prevent a concentration of wear on said bearings.

With the above and other objects in View, the invention has particularrelation to certain novel features of construction, operation, andarrangement of parts, an example of which is given in thisspecification, and illustrated in the accompanying drawings, wherein:-

Fig. 1 shows a vertical sectional view of the apparatus, and

Fig. 2 shows a plan view, partly broken away, and partly in section.

Referrring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the gures, the numeral Idesignates a casing having enclosed within it the gear case 2, which isenclosed above by a cover plate 3. Adjacent the gear case, the casing isformed approximately circular, forming the chamber 4 having the elevatedhorizontal partition 5, forming the bottom thereof. Supported on saidpartition there is the upstanding tubular spindle 6 having the wide base1 which is secured to said horizontal partition by means of suitablescrews, as 8.

There is a rotary table 9 forming a cover for the chamber 4, and whosemargin is formed with (Cl. 'M -606) the downwardly turned flange Il]which ts closely around the upstanding circular wall around the chamberIl. The rotary table 9 is formed with a central sleeve-like hub I Iwhich fits over the spindle 6. The upper end of the hub is closed by thecap l2 which may be bolted thereto by means of the set-bolts I3. Theupper end of the spindle 6 is reduced and between said reduced upper endand the hub II are the main roller bearings Ifl. The lower end of thehub II may also have roller bearings I between it and the base of thespindle.

The rotary table 9 is equipped with a suitable ring gear S which isenclosed within the chamber t and which is in mesh with a spur gear I'I,which is fastened on the sleeve I8. This sleeve rotates about a spindleI9 whose upper and lower ends are suitably anchored to the top andbottom of the gear case. Conventional anti-friction bearings are locatedbetween the sleeve I8 and the spindle I9 and xed on the lower end ofsaid sleeve I8, there is a bevel gear 2l! which is in mesh with anddriven by the pinion 2l. This pinion is xed on the inner end oi thedrive shaft 22, which rotates in suitable aligned bearings at one sideof the gear case, and which is adapted to be connected to a source ofpower. The shaft 22 is equipped with suitable anti-friction bearings, asshown. Means are thus provided for driving the rotary table 9. The table9 has an eccentric spindle 23 upstanding therefrom which revolves aboutthe main bearings I4 as the table 9 turns.

There is a circular disk 24 which has the central hub 25 and this hub istted intoand rotates in an upstanding bearing sleevey 26 which is formedeccentrically on, and upstanding from,

Vthe table 9. Within the hub 25 are the roller bearings 2'I whichsurround the spindle 23. The upper end of the hub 25 is closed by asuitable cap plate 2B which may be bolted, or otherwise secured thereto,and between this cap plate and the upper end of the spindle are theanti-friction bearings 29 which are located between the upper and lowerrace plates Sil, 3l.

The disk 24 must be mounted to clear the upper end of the hub I I of therotary table so that said disk may be freely revolved.

As hereinabove indicated, the power will be located 'centrally withrespect to the various wells, in the eld, to be operated, and theoperating rods, as 32, will radiate from said disk and will be connectedat their outer ends at the various pump jacks and at their inner ends tothe margin of the disk 24. The connection of each rod 32 to the disk 24is effected by means of a yoke 33 whichk is clamped to said rod andwhich embraces the margin of the disk and is pivotally connected theretoby the connecting pin 34, as shown in Fig. l.

In order that the line of thrust of the rods 32 may pass through thebearings I4, 27, inten mediate their ends so as to prevent any unduestress on said bearings, and to cause the wear to be distributed throughthe lengths of the bearings, the margin 35 of said disk 29 is downwardlyturned and is provided with bearings 36 to receive the pins 34Whichconnect the various yokes 33 to the disk 24.

It is obvious that as the table 6 rotates, the disk 24will becorrespondingly revolved, or oscillated, and the connecting rods 32 willbe reciprocated, thus operating the various pump jacks and pumps towhich the rods are connected.

The gear case 2 and the chamber 4 will be kept filled, or partly lled,with oil for lubricating purposes. The gears I6, I1, 20, ZI, as well asthe bearings I and the bearings of the shaft 22 will be thereby directlylubricated. A conventional pump 31 is located in the gear 'case and isoperated from the shaft 22 and this pump forces the lubricant throughthe pipe 38 into the tubular spindle G, and the lubricant overflows theupper end of said spindle, lubricating the spindle bearings and passesout through the` duct 39 and up through the axial channel 40 of thespindle 23, and over-flows the upper end of the tube 4I, which islocated in a transparent shield 42. This overflowing lubricant flowsback down and lubricates the bearings 29 and Z1 and passes through theports 43, 44, and on to the teeth of the gears I6, I1, and thence backinto the gear case 2. The pipe 38 has the branch 45 which conducts thelubricant to the bearings of the sleeve I8, and the oil nally flows backinto the gear case. The lubricating system described, however, is notconsidered to be a part of the invention disclosed.

The drawings 'and description disclose what is now considered to be apreferred form of the invention by way of illustration only, while thebroad principle of the invention will be defined by the .appended claim.

What I claim is:

A power for operating well pump jacks comprisng a bottom support, atubular upstanding spindle having a bottom flange detachably supportedon said support and whose upper end is reduced, a rotary table having asleevelike hub, which extends above and depends beneath said table andts over said spindle, upper, intermediate and lower bearings between thehub and spindle, an eccentric spindle upstanding from the table, abearing sleeve surrounding and spaced from said eccentric spindle andupstanding from the table, a disc having a central hub which ts closelywithin said upstanding sleeve and which surrounds said eccentricspindle, bearings between the eccentric spindle and the hub of saiddisc, means for rotating the table to revolve the disc about the tablespindle, the margin of the disc being downwardly turned and havingattaching means for radially extending pump actuating rods, said marginbeng located in a plane passing through the disc bearing and the uppertable bearing.
